有谁知道多晶硅生产尾气活性炭的技术要求吗？ 以下是cdi公司提供的活性碳干燥方案，对比你厂的活性碳干燥，是否符合。 drying procedure with the adsorber towers in manual, dry carbon in the following manner (this procedure may take 2 to 3 days for each adsorber): 1. close all feed and product valves on the adsorber being dried to prevent moisture from entering system piping. 2. using hot thermal fluid and the adsorber coils, heat the adsorber bed to 150°c. if the adsorbers are not supplied with thermal fluid coils, use hot nitrogen (~230°c) in the manner described below in step 3 to heat the adsorber beds. 3. using utility stations and flexible hose send clean nitrogen from the top of the adsorbers down through the 活性碳 beds and out to the atmosphere. it is common to see substantial amounts of water leaving with the nitrogen. 4. continue heating the adsorber while purging with nitrogen to the atmosphere until the bed temperature is 150°c, the outlet dew point is below -40°c, and the oxygen content is 0.1 vol%. 5. repeat for the other adsorbers using the same procedure.查看更多
帮忙翻译哈？ double valves are switched in such a way that one of the two will fulfill the most severe service to ensure proper sealing of the other 双阀门是如此动作的，其中一个阀门在最高工作承受状态充满介质以保证另一个阀门严密封口。查看更多
